The development direction of vehicle power supply technology

With the continuous development of vehicle equipment information, there are more and more vehicle electrical equipment, and the power consumption of additional vehicle equipment is gradually increased. The working location of the vehicle power supply is far away from the production site, and the energy supply has certain limitations; At the same time, the on-board power system not only has a large power consumption and high quality requirements for the on-board power supply, but also to avoid information loss and work loss caused by power failure. Therefore, the vehicle power supply system is required to have the characteristics of large capacity, safety and reliability, and uninterruptible power supply. If a single power supply is used, the converter must deal with large power and large electrical stress, which brings difficulties to the selection of power devices, switching frequency and power density improvement. And once a single power supply fails, the entire system crashes. Therefore, the use of distributed power system instead of a single power supply, through multiple power modules running in parallel, to provide high-power output is a direction of the development of vehicle power technology.
